SU LKY- PLOW.

SPECIFICATION forming part of Letters :Patent No. 225,538, dated March 16, 1880. Application filed December 5, 1879.

To all 'whom fit may concern:

Be it known that I, FREDEIGK J. SMITH, of Chicago, in the county of Cook and State of Illinc-, have invented certain new and useful Improvements in Sulky Attachments for Plows; and I hereby declare the following to be a full, clear, and exact description thereof, which wjl enable others skilled in the art to which my invention appertains to make and use the same,reference being had to the y accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Figure I is a perspective elevation; Fig. 2, a side elevation with part of the attachment cut away, and Fig. 3 a sectional detail.

The object of this invention is the construction of an improved sulky attachment for plows, by means of which the ordinary plow may be easily and conveniently converted into a sulky-plow, and it consists in certain novel arrangements, as will hereinafter be more fully explained in detail. r

In referring to the drawings, A represents an ordinary plow connected to the sulky attachment. B represents the wheels, b the axle, and C the skeleton frame-work which supports the several parts forming the sulky attachment. D denotes the seat for the accommodation of the operator. a is the hand-lever, moving in the guard a', and is used for the purpose of elevating or depressing the point of the plowshare. a? is the horizontal part, and a3 is the vertical part, of a connectingarm, being a continuation of the hand-lever a, and is constructed integral therewith. At a point near the lower end of the arm a3 is inserted a bolt, which secures the same to theY height, and it is quite essential to have some means of adjusting the plow to a parallel angle with the 'sulky attachment. This is acfulcrum-block c up or down, as may be required, to bring the plow to the proper angle with the snlky attachment.

To the lower end of the arm a3 is attached one end of the connecting-rod 5, the other end of this rod 5 being attached to clamp 6, this clamp being in turn secured to the handle-extension of the plow, as shown in the drawings. This clamp-connection should be made adjustable by having elongated bolt-holes, so as to be adapted to plows ot' different dimensions. By this arrangement ot' these parts the operator is enabled to control the operations of the plow through the medium of the hand-levera,.

The vertical support 7 forms a part of theguard c and is bolted to a part of the framework C. To the lower end of this support is attached a rectangular lever having arms S and 9. Arm 9 of this lever moves in the arc l0, which is provided with a series of perforations in the line ot its circle, as shown in Fig. 2 of the drawings. n

The object of the arm 9 and the arc l0 is to gage the depth of the furrow. For instance, if the arm 9 is placed at the first hole the furrow will be four inches in depth, if placed in the second hole it will be six inches deep, and so on`. The foot rest or lever l1 forms part of arm 9, and is constructed integral therewith, and by means of this foot attachment the operator is enabled to raise the plow clear from the ground when passing-from point to point.

'Arm 8 of the rectangular lever has connection with the plow-beam by means of the short arm 12 and arm I3, shaft 14C, connecting-rod 15, and the clamp 16, which is made to embrace the beam of the plow, and is made adjustable in the same manner as clamp 6.

The upright braces 17 and I8 are clamped to the axle b and form a part of the framework supporting the operating parts.

This form of construction and connection permits of an independent movement of the plow, and the wheels of the sulky attachment meeting with any obstructions or passing over an uneven surface does not interfere with the effective working of the plow.

Having thus described my invention, what I IOO l. The combination of the vertical inclined i bracket, With screw c', with the adjustable le.- ver fulcrum-block c, adapted to move up or down on said screw, the connecting-rod 5, clamp 6, and the plow A, as and for the purpose set forth. 2. The combination, With the hand-lever a, having the arm extension a? and c3, and the adjustable rack-frame cf, of the adjustable fulcrum c, the vertical inclined screw' cf, the connecting-rod 5, clamp 6, and the plow A, substantially as and for the purpose described.

3. The combination, With a rectangular lever consisting of arms 8 and 9, and having the foot-lever 11 integral therewith, of the arc 10, perforated in the manner shown and adapted to secure the arm 9 in different positions, as herein described, the vertical arm 12, the horizontal connection 13, shaf't 14, connecting-rod 15, clamp 16, and the plow" A, substantially as and for the purpose herein described.

4. 1n a sulky attachment for plows, the combination of the following elements, consisting of the handlever a, having extensions t2 and a3, the adjustable part c, the vertical inclined screw c', connecting-rod 5, clamp 6, the rectangular lever consisting of arms 8 and 9, the arc 10, vertical arm 12, horizontal arm 13,- shaft 14, connecting-rod 15, clamp 16, and the plow A, all constructed and arranged as herein shown and described.
